请高手帮我翻译：你是因为我而受苦，我无能为力，下辈子，我还你！

You are suffering because of me, I could do nothing about it, my next life, I have you!

这样好不好呢

I cannot do anything for what you have suffered because of me. I will reward your kindness if I have the next life.

说句题外话, 您这是向谁忏悔呢??没必要吧...

All difficulties you suffered should be imputed to my inability. But I will pay back to you by all means in future.
